The Sea of Galilee is a freshwater lake in Israel. It is the lowest freshwater lake on Earth and the second-lowest lake in the world (after the Dead Sea, a saltwater lake), at levels between 215 metres (705 ft) and 209 metres (686 ft) below sea level. It is approximately 53 km (33 mi) in circumference, about 21 km (13 mi) long, and 13 km (8.1 mi) wide. Its area is 166.7 km2 (64.4 sq mi) at its fullest, and its maximum depth is approximately 43 m (141 feet). The lake is fed partly by underground springs, although its main source is the Jordan River, which flows through it from north to south.

The Sea of Galilee is situated in northeast Israel, between the Golan Heights and the Galilee region, in the Jordan Rift Valley, the valley caused by the separation of the African and Arabian Plates. Consequently, the area is subject to earthquakes, and in the past, volcanic activity. This is evident by the abundant basalt and other igneous rocks that define the geology of Galilee.
